Specification of Letters Patent.

Patented Aug. 8, 1922.

To @ZZ whom t may concern.:

Be it known that I, Jaime P. KELLY, a citizen oi' the United States otAmerica, residing at New York city. New York county, N. Y., haveinvented a new and useful Cord rfip, of which the following is aspeciiication.

My invention relates to improvements in devices of the character setforth in my Patent #1,392,339, dated October- 1921. The main object or"my present invention is to provide a simple and inexpensive form ofconstruction, the parts or which may be readily assembled on the end oi?a cord and securely held in place but readily separable when desired.

In my former patent l have illustrated forms or' tips in which there arecentral and lateral gripping members.

My present invention contemplates the use of a sleeve and a clampingmember with a head provided with a recess or perforation into which aninstrument such as a pin may be inserted for holding the head whilethesleeve is pulled along the cord so as to separate the parts. Theclamping member may engage the cord in any suitable manner, but I haveillustrated herein as one *form a particularly simple construction, inwhich the clamping member is in the form of a pin Vadapted to be stuckthrough the cord transversely and bent over and held by the sleeve.

Fig. 1 is a side view of one form ot cord tip embodying improvements ofmy invention. Y

Fig. 2 is a perspective view showing the sleeve slipped back along thecord.

Fig. 3 is a view of the clamping member before it is bent over.

Figs. 4 and 5 are perspective views of other Jforms of lateral clampingmembers having instrument receiving recesses in their heads.

Fig. 6 is a perspective view of a central tip clamping member with acoiled head and recess.

Fig. 7 is a plan view of another form of clamping member with side jawsand a recess in the head.

Fig. 8 is a longitudinal sectional view of another form of cord and tipof my invention.

Fig. 9 shows the parts of another form of tip, the sleeve being insection.

The cord or string 10 may be oi' any suitable material, such, forinstance, as braided, twisted, or woven threads such as are commonly thelike. The particular cross-section such as round. oval, or flattened isimmaterial. The sleeve l1 is in the form of an open ended tube ofsuitable cross-section, and will usually be or" somewhat less transverseinternal area than the end oit the cord so that it will t snugly. rTheclamping member is in the form of a pin having a shank 12 and a head 13.The pointed end or tip 14 of the pin is adapted to be stuck through thecord 'and then bent over as shown in Fig. 2. l/hen the sleeve 11 ispulled out toward the end it compresses the parts 12 and 14 into thesides of the cord and thus increases the gripping eiiect. The main shankof the pin may be provided with barbs or tongues 15 adapted to stickinto the cord and increase the gripping effect. The back or shoulder 16of the head may be tapered or inclined so as to assist in centering thehead with respect to lthe end of the sleeve 11.

To remove the tip, for instance for the purpose of shortening the cordand reapplying the tip, it is necessary to slide the sleeve 11 alongtheend of the cord away from the head 13. When the partsV are made so as tofit together snugly, this operation et separation is sometimes ratherdifiicult. To facilitate the separation therefore provice a recess suchas 17 into which the point 'of some instrument such as a pin may beinserted to hold the head and clamping member while the sleeve isslipped vback into the position'shown in Fig. 2. It will be obvious thatthe end or tip 14 may then bev withdrawn from the cord. To preventinterference with this withdrawal, the end or tip 14 is preferably leftsmooth. To re-apply the device, the cord is cut at the desired point andthe tip 14 of the pin pushed through the cord and bent over as shown inFig. 2, and the sleeve 11 pulled down to the end against the rearshoulder of the head. This provides a very secure tip which cannotbecome disengaged accidentally.

In the form shown in Fig. 4 the shank 12 is flattened and adapted to lieagainst one side of the cord. In this form t-he barbs or tongues 15 areformed by punching small triangular holes. The recess 17 instead otbeing entirely in the exposed part of the head may be in the edge of thehead so that less of it will be exposed beyond the end of the sleevewhen the parts are assembled. As the tapered point of an ordiemployed inmaking shoe strings and nary pin or needle (not shown) is inserted intothe outer part of the recess 17'; it Will begin to force the sleeveavvay from the head.

In the Vform shown in Fig. 5, the barbs or teeth 15""are formed ontheedges ot the shank of the clamping member. f

The form of device shown in Fig. 6 has a shank 12'?1 adapted to `beinserted into the center ot the end of; the cord, and the head 13? isformed by ooiling the Wire so as to leave an instrument receiving recess17a.

The form of device shown in Fig. 7 is termed by bending a piece of Wireor strip of material; so as to provide two` jaws l2", one of Which ispreferably longer than the other soas to facilitate assembly of thesleeve over the jaws. The head portion 13b is formed so as to provide arecess 171 for the insertion of a holding instrument-` In, the form ofdevice shown in Fig. 8, the clamping or gripping member may be stampedfrom sheet metal with its head 13 so. shapedi as to leave` a recess 17cat the end of the sleeve 11.

In the form` shown in Fig. 9,.the tip 14d ot` the shank oi' the grippingmember is long enough to project of the sleeve 11d so that pressure maybe applied at this end through the body `ot the cord to start theseparationmovement of the sleeve with respect to the gripping member. In`this ease, the recess 17d is normally concealed by the end of thesleeve, but is exposed bypressing on the opposite end;` 14s so that apin may be inserted into the recess 17d `for completing the separationmovement* I claim:-

1. A cord tip device comprising a head,- ed pin with a shank forembracing one side of the end of a cord, said pin having another portionor extending transversely through. the. `cord" and al tip portion conabit beyond the end nected to the transversely extending portion 3. Acord tip comprising a gripping member With a head at one end andabendable tip adapted to be inserted through the end ot a cord, and asleeve adapted to slide along the end of the cord for holding saidmember and its tip in place.

1l. Acord tip comprising a gripping member having a head With aninstrument receiving recess and a bendable, portion adapted to be passedthrough the end oi' the cord and a sleeve holding the parts in place.

5. A cord tip comprising a gripping element having a head With a taperedcentering shoulder and a toothed shank adapted to lie. alongside theendof the cord, and a sleeve adapted to slide along the cord and to hold.`said shank in place, said sleeve abutting against said tapered shoulderWhen said parts are assembled.

6. A cord tip comprising a gripping mem* berhaving a shouldered headWith an instrument receiving recess and a sleeve embracing the endV of acord and holding said gripping member in place, said sleeve abuttingagainst said shouldered head.

"t". A cord tip comprising a gripping member having ahead vvithl atransverse passage for receiving the point of; a holding instrument anda shank for engagingy the end of a cord,'and a sleeve embracing the endof' cord adjacent Said heald for holdin@r sai Ori 1n mem er 1n ace.
